Gamma-ray bursts could test quantum gravity
Gamma-ray bursts appear to be related to the deaths of massive stars. Amelino-Camelia and colleagues claim that if the difference in the arrival times of photons with different energies can be measure...
Superfluidity seen on microscopic scales
Bulk superfluid helium has many unusual properties – it can flow up walls and through narrow pores without resistance. Helium-4 and helium-3 become superfluid below 2.12 and 0.003 Kelvin respect...
Amplification of matter waves
Bose-Einstein condensation itself was only observed for the first time in 1995. There has been intense interest in the process ever since because of the unique quantum behaviour displayed by matter in...

Against ‘measurement’: John Bell on our continuing struggles with quantum mechanics
Uncertainty over terms such as ‘apparatus’ is still rife in serious discussions of quantum mechanics, over 60 years after its conception, says John Bell
